Catholic Left: Pope Francis "Has Some Splainin' to Do"

Some on the Catholic left seem to have reservations about the fact that Jorge Mario Bergoglio (a.k.a., as of yesterday, Pope Francis) was not immersed in the so-called "liberation theology" movement that was rampant in Latin America from the late 60s through the early 80s until Pope John Paul II rooted it out.

This quote in the comments following the linked post is just precious:

"... practically any non-liberation theology bishop from Latin America probably has explaining to do. I hope Pope Francis is forthcoming about this."

Yes, how dare Pope Francis not involve himself in something his predecessor popes described as a heresy?
